returning from the DHCP server back to the VIP of the Cluster.

B.
A link collision due to more than one NAT symbolic link being created for outgoing

connections to the DHCP server.

C.
An inbound collision due to a connections table check on pre-existing connections.

D.
An outbound collision due to a Rule Base check, and dropped by incorrectly configuring
DHCP in the firewall policy.
